4. Geometrically linear means that the electron groups have what angle?
5. Geometrically trigonal planar means that the electron groups have what angle?

7. You have been given a 0.325 L canister containing a gas. The pressure gauge on the canister reads 721 mmHg, and the temperature gauge reads 305.15 K. The piston on the canister was pushed to compress the gas to 0.286 L, thereby increasing the pressure to 901 mmHg. What is the new temperature in Celsius? Remember sig figs.
8. I have a pressure cooker in my underground lair that is brewing a diabolical solution. I set everything up and went upstairs, but forgot to write down the initial temperature. I know the starting volume was 1.00 L. When I came downstairs later to check on it, I see that the volume increased to 1.10 L, and thermometer read that the temperature was now 528.15 K. What was the starting temperature when I left( in ° C)?
9. Think back to Lesson one when we talked about density. Now think about it--my kids love balloons, and then are always laying around the house. Suppose one was laying by the window at night when they went to bed, but the next day, when the sun came up, it warmed the gas( air) that was in the balloon. What would be true about the density of the air in the balloon?
